Review on 🔌 YONHAN Motorcycle USB Charger SAE to USB Adapter with Dual USB Type C PD & Quick Charge 3.0, Voltmeter & ON/Off Switch, 36W Total Output, 3 Installation Options - Ideal for Smartphones, Tablets, GPS by Jon Dunn

So I plugged this device in and checked but it wouldn't turn on. I have over 10 years experience in automotive electronics and I knew my methods were right. After investigation they had the red wire as negative and the black wire as positive. Good. After I reversed their mistake, the charger actually works as intended. It's able to charge my Pixel4XL quickly, which was my main concern. Time will tell how durable it is.
